目的探讨水平半规管良性阵发性位置性眩晕(HSC-BPPV)患者管结石复位过程中耳石移位误入其他半规管的发生率、识别方法和治疗策略。方法对98例HSC-BPPV患者应用红外线视频眼动记录仪分析其变位试验诱发的眼震特点,进行分型、定侧,并采用相应的耳石复位法治疗,分析复位过程中出现耳石移位误入其他半规管的情况。结果 63例水平向地性眼震(水平半规管BPPV)患者复位过程中转变为后半规管BPPV患者5例;35例水平背地性眼震患者(水平半规管嵴帽结石)在Gufoni法复位后变为管结石4例;总发生率为9.18%(9/98)。结论 HSC-BPPV患者在复位过程中可能发生耳石移位至其他半规管,可通过仔细观察并正确识别眼震方向发现;水平半规管嵴帽结石在转化为管结石后可以进行管结石复位治疗。     

水平半规管性良性阵发性眩晕(HSCBPPV)

BPPV是一种外周性迷路综合征,它是由一定的位置变化而引起的短暂、剧烈的眩晕发作。常伴有自主神经症状。患者在向患侧迷路倾倒时即诱发眩晕和眼震。眼震特点是,呈扭转性、有典型的潜伏期,发作短暂,不超过30秒、恢复坐位时眼震方向改变及呈可疲性。但近来发现在50％的BPPV病例中在悬头位时有继发性眼震出现。其发病机理认为可能是由耳石膜的耳石脱落沉积于后半规管(PSC)嵴帽所致。Schuknecht称之为嵴顶沉石症。近来在这种BPPV病例中发现其症状虽与BPPV相似,但与PSC嵴顶沉石症不尽相同。由此作者推测其病程可能起源于水平半规管(HSC)。

上半规管良性阵发性位置性眩晕的诊断及治疗

目的探讨上半规管良性阵发性位置性眩晕（benign paroxysmal positional vertigo，BPPV）的诊断和治疗。方法回顾性分析了上半规管BPPV患者31例，并对所有患者采用管石复位法治疗后的效果进行评估。结果在Dix-Hallpike检查中，所有患者均诱发出垂直向下的眼震。22例（70．97％）患者一侧诱发出眼震，其中17例眼震伴有扭转成分，5例眼震不伴扭转成分。其余9例（29．03％）患者双侧诱发出现眼震，眼震伴有扭转成分的7例，其中2例眼震扭转方向指向同一侧，4例眼震的扭转方向不固定，1例患者仅一侧出现扭转成分。另外2例患者眼震不伴扭转成分。受累侧别明确诊断的19例（61．29％），其中11例为左侧上半规管受累，8例为右侧上半规管受累。受累侧别未明确诊断的12例（38．71％）。所有患者中，11例（35．48％）患者同时合并后半规管受累。对所有患者采取管石复位法治疗，21例（67．74％）痊愈，29例（93．55％）有效、2例（6．45％）无效。其中首次治愈14例（45．16％），平均治愈次数为1．71次。随访期间5例复发。结论上半规管BPPV临床中少见。在变位检查中，眼震的扭转成分较弱，临床中不易观察。在部分单侧上半规管BPPV患者中，双侧检查均能诱发眼震。管石复位法是治疗上半规管BPPV简单有效的手段。

Benign paroxysmal positional vertigo

Benign paroxysmal positional vertigo (BPPV) is characterized by positional vertigo (brief attacks of rotatory vertigo triggered by head position changes in the direction of gravity) and is the most common peripheral cause of vertigo. There are two types of BPPV pathophysiology: canalolithiasis and cupulolithiasis. In canalolithiasis, otoconial debris is detached from the otolithic membrane and floats freely within the endolymph of the canal. In cupulolithiasis, the otoconial debris released from the otolithic membrane settles on the cupula of the semicircular canal and the specific gravity of the cupula is increased. Consensus has been reached regarding three subtypes of BPPV: posterior-canal-type BPPV (canalolithiasis), lateral-canal-type BPPV (canalolithiasis) and lateral-canal-type BPPV (cupulolithiasis). In the interview-based medical examination of BPPV, questions regarding the characteristics of vertigo, triggered movement of vertigo, duration of vertigo and cochlear symptoms during vertigo attacks are important for the diagnosis of BPPV. The Dix–Hallpike test is a positioning nystagmus test used for diagnosis of posterior-canal-type BPPV. The head roll test is a positional nystagmus test used for diagnosis of lateral-canal-type BPPV. When the Dix–Hallpike test is repeated, positional nystagmus and the feeling of vertigo typically become weaker. This phenomenon is called BPPV fatigue. The effect of BPPV fatigue typically disappears within 30 min, at which point the Dix–Hallpike test again induces clear positional nystagmus even though BPPV fatigue had previously caused the positional nystagmus to disappear. For the treatment of BPPV, sequential head movements of patients can cause the otoconial debris in the semicircular canal to move to the utricle. This series of head movements is called the canalith repositioning procedure (CRP). The appropriate type of CRP depends on the semicircular canal in which the otoconial debris is located. The CRP for posterior-canal-type BPPV is called the Epley maneuver, and the CRP for lateral-canal-type BPPV is called the Gufoni maneuver. Including a time interval between each head position in the Epley maneuver reduces the immediate effect of the maneuver. This finding can inform the development of methods for reducing the effort exerted by doctors and the discomfort experienced by patients with posterior-canal-type BPPV during the Epley maneuver.     

Particle repositioning maneuver for benign paroxysmal positional vertigo

The recent demonstration of free-floating particles in the endolymph of the posterior semicircular canal in patients with benign paroxysmal positional vertigo (BPPV)¹ has renewed interest in the physiology and treatment of this entity. The particle repositioning maneuver (PRM) relocates the free-floating particles from the posterior semicircular canal back into the utricle, relieving the patient of bothersome, often long-standing vertigo. This report represents a prospective study of 27 consecutive patients seen with a diagnosis of BPPV. Eighty-four percent of the patients treated with the particle repositioning maneuver who had no other associated pathology were cured or significantly improved with this new technique. Two patients who failed conservative management went on to surgical intervention with the posterior semicircular canal occlusion. The authors find the particle repositioning maneuver effective for many patients with benign positional vertigo and recommend it as the first-line treatment modality for BPPV.     

水平半规管良性阵发位置性眩晕的诊治

目的探讨水平半规管良性阵发位置性眩晕（horizontalcanalbenignparoxysmalpositionalvertigo,HC-BPPV）的诊治方法。方法回顾分析1996年7月～2000年3月间南京医科大学第一附属医院耳鼻咽喉科诊治的9例HC-BPPV患者的临床资料。对所有患者全面采集病史,行纯音听阈测试和耳神经学检查,常规施行仰卧侧头位试验和Dix-Hallpike试验,并按Barbecue翻滚法行耳石复位治疗。结果本病以头位改变所诱发的短暂旋转性眩晕为特征,常见诱发体位为床上翻身（9/9例）和转头（5/9例）。仰卧侧头位试验可诱发水平向地性眼震,无潜伏期和疲劳性。采用Barbecue翻滚法治疗后全部患者症状立刻消失,随访4～15个月无复发。结论根据典型表现和体位试验结果,可明确区分水平半规管性和后半规管性BPPV以及其他原因引起的眩晕。Barbecue翻滚是治疗HC-BPPV有效的方法。     

Horizontal canal type BPPV: bilaterally affected case treated with canal plugging and Lempert's maneuver

A 54-year-old woman complained of positional vertigo. During 3 months' observation, the patient showed mostly geotropic or apogeotropic nystagmus due to right canalolithiasis or cupulolithiasis, however, she sometimes showed nystagmus which suggested left horizontal canalolithiasis. We suspected that she suffered from bilateral horizontal canal type benign paroxysmal positional vertigo (BPPV) and performed Lempert's maneuver for both directions, however, they were ineffective. She underwent canal plugging for right horizontal canal. After surgery she showed no positional nystagmus of right horizontal canal origin. However, apogeotropic nystagmus of the left horizontal canal origin was still observed. This nystagmus changed to geotropic nystagmus and finally disappeared following Lempert's maneuver for the left side. Bilateral horizontal canal BPPV is difficult to be resolved, probably because physical treatment for one side would move debris to the cupula in the other canal. Canal plugging combined with Lempert's maneuver to the other side is one treatment option for intractable bilateral horizontal canal BPPV.     

Benign paroxysmal positional vertigo due to a simultaneous involvement of both horizontal and posterior semicircular canals

From April 2001 to November 2003, we investigated 8 patients with benign paroxysmal positional vertigo (BPPV) that was suspected to simultaneously affect both the horizontal and posterior semicircular canals (HSCC and PSCC). These cases showed typical vertical-torsional nystagmus induced by the Dix-Hallpike maneuver, followed by a horizontal nystagmus. They also showed a direction-changing geotropic or apogeotropic positional nystagmus triggered by lateral head rotations in the supine position. Using the three-dimensional analysis of the positional nystagmus, the rotation axis of the positional nystagmus had a component perpendicular to the plane of PSCC and another component perpendicular to the plane of HSCC. All these findings suggest that BPPV in these patients was a combination of posterior and horizontal canal BPPV. The observation of a vertical-torsional positional nystagmus should prompt the specialist to perform not only the canalith repositioning procedure, but also to execute lateral head turns in the supine position.     

水平半规管良性阵发位置性眩晕的诊治

Time Course of Recovery After Epley Maneuvers for Benign Paroxysmal Positional Vertigo

The canalith repositioning maneuver (CRP) of Epley is an effective treatment for benign paroxysmal positional vertigo (BPPV). While CRP has been advocated by some as a “single treatment” for BPPV, others have had less uniform results for this self-limited disorder. In order to better define the role of CRP in relieving vertigo, we studied the time course of recovery in 27 consecutive cases of BPPV. We recorded nystagmus after each head maneuver and at each evaluation until complete resolution took place, using absence of nystagmus as a strict criterion for cure. We found that while 93% of patients improved, many had persistent nystagmus at the first evaluation, and in only 63% was resolution clearly related to a CRP session. We believe that in certain cases, the effect of CRP may be due to adaptive conditioning, rather than particle redistribution.     

Effectiveness of the particle repositioning maneuver in subtypes of benign paroxysmal positional vertigo

OBJECTIVES: To assess the efficacy of the particle repositioning maneuver (PRM) in patients presenting with idiopathic benign paroxysmal positional vertigo (BPPV) compared with those with evidence of additional peripheral vestibulopathies. METHODS: Retrospective administration of the Dizziness Handicap Inventory (DHI) to 41 patients with primary BPPV and 31 patients with secondary BPPV to subjectively evaluate their symptoms before and after the PRM. RESULTS: Both groups indicated a marked improvement in symptoms after the PRM. Only two patients reported an increase in their symptoms after the PRM and both had secondary BPPV. CONCLUSIONS: The PRM was found to be highly effective in all forms of BPPV, but careful history and judicious testing may identify patients requiring additional intervention to relieve their symptoms.
